Abstract: A dispersion to catalyse polysiloxanes for treating fabrics comprises (A) 100 parts by weight of the reaction product of a titanium compound of formula TiR4, where R is an alkoxy radical or chlorine atom, with from 1 to 4 mols. per mol. of the titanium compound of a dihydric alcohol containing 6 to 12 carbon atoms and containing the structure <FORM:0984993/C3/1> a partial hydrolysate of such reaction product, (B) from 5 to 50 parts by weight of a monocarboxylic acid containing at least 8 carbon atoms, and (C) at least 100 parts by weight of water.  The dispersion may be mixed with an organosilicon dispersion to give a dispersion containing 0.5 to 20% by weight of a hydrocarbon-solvent-soluble polysiloxane having an average of 1.75 to 2.5 substituents per silicon atom, the substituents being hydrogen atoms or monovalent hydrocarbon radicals or halogenated hydrocarbon radicals containing 1 to 18 carbon atoms, and there being an average of 0.05 to 1 silicon-bonded hydrogen atom per silicon atom; the dispersion contains 0.4% to 7% by weight of titanium calculated on the weight of organosiloxane.  The dispersion also may contain 0.5% to 20% by weight of a crease-proofing agent, e.g. a urea-formaldehyde resin, a melamine-formaldehyde resin, or a cyclic urea, and a catalyst, e.g. zinc nitrate, an amine hydrochloride or magnesium chloride. The dispersion of the invention may be used with the silicone composition described in Specification 835,516.  In examples, dispersions contain the reaction product of a titanium ortho ester with 2-ethyl-1,3-hexanediol and the material obtained by partially hydrolysing this reaction product, the reaction product of TiCl4 with 2-ethyl-2-n-butyl-1,3-propane diol, the reaction product of Ti[OCH2CH(CH3)2]4 with 2-methyl,1,3-pentane diol, the reaction product of Ti[OCH2CH(CH2CH3)(CH2)3 CH3]4 with 4,5-octanediol, and the reaction products of Ti[OCH(CH3)2]4 with 3,4-diethyl-2,5-hexanediol and with 2-propyl-1,3-heptanediol; the monocarboxylic acid used is oleic acid and the polysiloxanes are a trimethylsilyl-end-blocked methyldydrogensiloxane liquid, a trimethylsilyl-end-blocked dimethylsiloxane liquid, a hydroxyl-end-blocked dimethyl-siloxane liquid, a copolymer of dimethylsiloxane and <FORM:0984993/C3/2> an amylhydrogensiloxane, octadecylmethylsiloxane, chlorophenylmethylsiloxane, a copolymer of dimethylsiloxane, monomethylsiloxane and monoethylsiloxane, and a copolymer of dimethylsiloxane and HSiO1.5; the dispersions also contain crease-proofing agents and catalysts therefor, solvents and emulsifying agents. Lists of other suitable ingredients are given. Specification 790,038 is referred to.ALSO:Glass fabrics are treated with a dispersion comprising (A) 100 parts by weight of the reaction product of a titanium compound of formula TiR4, where R is an alkoxy radical or chlorine atom, with from 1 to 4 mols per mol of the titanium compound of a dihydric alcohol containing 6-12 carbon atoms and containing the structure:  <FORM:0984993/B1-B2/1> , or a partial hydrolysate of such a reaction product, (B) from 5 to 50 parts by weight of a monocarboxylic acid containing at least 8 carbon atoms, and (C) at least 100 parts by weight of water, mixed with an organosilicon dispersion to give a dispersion containing 0,5-20% by weight of a hydrocarbon-solvent-soluble polysiloxane having an average of 1,75-2,5 substituents per silicon atom, the substituents being hydrogen atoms or monovalent hydrocarbon radicals or halogenated hydrocarbon radicals containing 1-18 carbon atoms, and there being an average of 0,05-1 silicon-bonded hydrogen atoms per silicon atom; the dispersion contains 0,4-7% by weight of titanium calculated on the weight of organosiloxane.
